The HB436 (and HB439) intelligent three‑phase voltage meter provides digital filtering, alarm functions and configurable measurement ranges. It operates from an AC/DC power source of 85‑260 V and supports input voltages up to 500 V (or 100 V) with selectable 50 Hz or 60 Hz frequency.
The manual explains panel layout, parameter setting procedures (including wiring mode, range, voltage‑line selection), alarm threshold configuration, and provides wiring diagrams and application examples for three‑phase three‑wire and four‑wire installations. This manual is written in Chinese.

Enter the parameter group P‑SN and select either 500 V or 100 V as the range; the default is 500 V.
Set the parameter "unit" to V for volts or KV for kilovolts in the parameter group.
Set the Line parameter to 3‑4 for three‑phase four‑wire mode; for three‑phase three‑wire use 3‑3.
